Review on ๐Ÿ”† Super Bright GRV T10 921 194 LED Bulb, 25-2835 SMD, Warm White, DC12V, Pack of 20, Ideal for RVs, Campers, Cabinets, and Dome Lights (2.0 Generation) by Frank Harwood

Revainrating 5 out of 5

I've tried 8 LED brands, these are the best for NATURAL warm white light.

I'm VERY picky about lighting. I tried 8 different T10 LEDs and ended up returning them all because they were either a gross, lifeless ice blue that made my car look like a morgue, or a ridiculous orange/yellow "amber" color that looked just as unnatural . LEDs ALMOST A PERFECT MATCH WITH STANDARD/OEM HALOGEN LIGHTS! They're also very bright. Brighter than almost everything I've tried, including Auxito, my favorite lighting brand (they make amazing LED headlights). Can't speak to long-term quality as I've only plugged them into a desktop (I do electronics repairs) but they seem to be on par with other lightbulbs I've tried. Not sure if I trust the bent wire connection point, but time will tell. If these lights are terribly unreliable in my 200 Toyota Land Cruiser, I'll update my review. PS: I just hooked them up to a variable DC power supply. Their brightness dims down to about 3V, after which they are very dim but still glow (only the top LED seems to turn on below about 5V). No flicker is seen between 10V (12V minus 1.8V voltage drop for the diode). ) up to approx. 3V. So yes, they are definitely dimmable!
